afternoon coin whores,
most alts are likely to worth 0, but I can tell you what are in my stash, they have the most chance to survive, reasons are:
LTC - the classic alt, has acceptances
PPC - the original POS
XPM - the original prime mining
Ripple - I got a chunk on the first giveaway, so I sit on it too lazy to covert to btc
MasterCoin - aka the greed coin
PTS - I don't have it but it might be something
well 2012-2013 were all about new schemes of money distribution coins, I think 2014 will be the coins for distributed exchange/smart property and what not
honestly, when BTC hit 10k$ by the end of 2015, I could no care less of alts live or die.
XPM is a "sleeping giant" imho!!!
